DiskSuds finds what’s quietly filling your Mac, shows exactly how much each thing would free, and lets you clear it with complete confidence.
Smart Scan finds caches, logs and developer files you don’t need, broken startup items, and anything waiting in the Trash.
This is a live simulation with example data. Nothing on your Mac is read.
Deep Clean
DiskSuds checks each app’s own cache, logs, Xcode and package-manager caches, old installers and the Trash — in seconds, not a disk-wide guess. A folder of yours that happens to be called “Logs” is never touched.
Explore
A living map of your disk. Every rectangle is a folder sized by the space it takes. Click into the big ones, step back out, and add anything you no longer need to Cleanup.
Click a folder to step inside. Example data.
Large Files
DiskSuds walks every folder — including the hidden ones search skips — and shows when each file was last opened, not just modified. Files in iCloud Drive can be removed from this Mac and kept in the cloud.
Duplicates & Similar Photos
Every duplicate is confirmed byte for byte. Then DiskSuds suggests the original to keep — not the first one alphabetically, and never the one named “copy” sitting in an archive folder.
Apps
Dragging an app to the Trash leaves its caches, logs, preferences and launch agents behind. DiskSuds shows the whole footprint and removes what belongs to that app alone.
Checks apps, startup items and downloads against Apple’s own XProtect malware signatures — and removes a threat together with whatever relaunches it.
See every helper that launches with your Mac, which app installed it, and broken ones left by apps you removed. Quarantine instead of delete, and restore any time.
Clear browsing history and cookies for Chrome, Brave, Edge, Arc and more. Bookmarks, passwords and autofill are never touched.
Built to be trusted
A cleaner is only as good as its worst day. So we tried to trick DiskSuds into deleting the wrong thing — and made it refuse, every time. Pick a trap.
Honest numbers
APFS clones and hard links share data between files, so deleting them can free far less than they appear to use. DiskSuds measures the difference before you clean — and reports what was really freed after.
Developer caches on one of our Macs: the same files, measured both ways.
Your final say
Always at hand
Storage, memory, CPU and network at a glance from the menu bar. Eject drives, see what’s keeping your Mac busy, and get a gentle nudge when space runs low.
Your Mac has room to breathe.

Not without you choosing it. DiskSuds only preselects things apps recreate on their own — caches, logs and developer build data — and you review every item before anything happens. Anything you created goes to the Trash, where Finder’s Put Back restores it. Mail, Messages, Photos libraries, Keychains and your account folders are never touched by any feature.
Download DiskSuds and look around: map your disk, see what’s taking room, and find what could be cleared. Buy when you’re ready to clean.
No. DiskSuds is $29.99 once. It includes a year of updates, and the version you own keeps working after that. It works on one Mac at a time, and you can move it to a new Mac.
macOS protects folders like Desktop, Documents and Mail. Full Disk Access lets DiskSuds measure them without asking folder by folder. It’s optional — DiskSuds still works without it, and it never reads the contents of your files, only their sizes and dates.
No. Scanning, comparing photos, checking for malware and cleaning all happen on your Mac. DiskSuds doesn’t upload your files or scan results.
If you choose to, DiskSuds can also clear system-wide caches and old system logs and manage startup items for all users. macOS asks you to approve its small helper first; it can only do those specific things, only DiskSuds can use it, and it quits when idle.
